Outrage over picture of baby breast-feeding

The response to this picture on a parenting magazine is completely stupid. Are people really so uncomfortable with seeing the side of a mother's breast when she's feeding her infant?

I had to laugh at the following:

• One mother who didn't like the cover explains she was concerned about her 13-year-old son seeing it. "I shredded it," said Gayle Ash, of Belton, Texas, in a telephone interview. "A breast is a breast — it's a sexual thing. He didn't need to see that."
• "I'm totally supportive of it — I just don't like the flashing," she says. "I don't want my son or husband to accidentally see a breast they didn't want to see."
• "Gross, I am sick of seeing a baby attached to a boob," wrote Lauren, a mother of a 4-month-old.

I mean, seriously? People are seriously offended about this? Don't these people have lives? A breast doesn't always have to signify a sexual thing, and breast-feeding is natural. I've never seen a woman just whip it out in public. Most women try to be as discrete as possible, while serving the needs of their babies. I honestly can't understand how people would be so squeamish about such a thing.
